The six-episode plot follows DS Hana Li partnering with embassy security chief Clay Brody to catch a hitman, while MI5 Director General Madeline Delaney handles the airborne crisis; personal backstories and rivalries drive character arcs, not identity politics. Jing Lusi returns as the capable British-Chinese lead Hana Li and Lesley Sharp as the authoritative MI5 head—both original characters whose competence fits the thriller genre without activist framing or lectures. Martin Compston joins as the new male co-lead Brody, with all major roles created for the series and no established-character swaps or source-material alterations.

Minor incidental elements include a diverse original cast and strong female protagonists in high-stakes roles, plus Common Sense Media noting themes of family and culture tied to Hana's background, but these remain organic and secondary to the conspiracy narrative. Audience complaints labeling it 'woke' focus on female competence or sidelined male characters rather than explicit messaging, and no creator statements emphasize social justice. The premise collapses without the corruption and murder plot, confirming low centrality of any progressive elements. Casting evidence: Casting research is incomplete or contains unresolved comparisons; overall casting fidelity has not been established.
